Abstract: Today's best magnetic materials show almost analytic behavior. This is used here todevelop a formalism, which deduces positional errors of magnet blocks from a measuredmultipole spectrum of a permanent magnetic quadrupole. This leads to the possibilityto correct for the positional errors and to reduce unwanted harmonics. Even harmonicsresulting from the slight dependence of magnetization of intemal field can be reducedby this method. Further optimization can be done by a sorting algorithm especiallydeveloped for this quadrupole as each segment is composed of several similar magneticblocks interchangeable between different segments.
